I'm also wondering why those of us that enjoy playing with classic teams weren't given the ability to edit the generic players in 2K12. It's silly that we have to buy a DLC pack for a feature that should have been in the game.
2K11 has so many great rosters that there is no reason to give the game up. I find myself playing it more now than 2K12; I'd rather played a fully patched game than a game that I know still needs work. I'll come back to 2K12 after a comprehensive gameplay patch, but until then, it's 2K11 for me.
